You'd be better served learning how to setup and use:

  • backups (and test them)
  • automate your reinstall (see ansible)
  • firewalld (RHEL/Fedora) or ufw (Ubuntu)
  • fail2ban
  • SELinux (RHEL/Fedora) or AppArmor (Ubuntu)
  • disable SSH via password, use keys only
  • adblocker (like ublock origin) - credit to whale@lemm.ee for the idea below

For the automating of reinstalls what do you mean?

Is it just a playbook that installs the distro, them installs the same packages, and then restores things like /home from backup?

That, and:

  • put down config files that were modified
  • enable/start services that were installed
  • modify the firewall to open necessary ports

Basically: put everything back as it was right before the ransomware encrypted your system on you.

Then of course - fix what you did wrong that got you compromised. ;-)

How would you determine the configs that were modified? What do you mean put down?

[-] GnomeComedy@beehaw.org 1 points 1 year ago

Ideally you keep your configs in a git repo (like github). You know what's modified because you're the one who modified them. If you modify them - put that config file in the git repo.

As for "put down" I just meant copied to the system (from github) by your automation (like ansible)
